I buy violin strings from either
http://www.thestringzone.co.uk/ or
http://www.stringmail.co.uk/ depending which is cheaper at the time (don't forget postage!).
I'm pretty sure they both do cello strings as well.

I use thestringzone as they have always delivered the correct items promptly.
I do not use stringmail as only time I ordered from them they sent the wrong strings. I had to phone them several times to get them to send me the correct strings and when they finally appeared I had to collect them from the post office and pay for the postage as they had not paid for it. I also had to return the incorrect strings at my own expense. So for me it ended up being an expensive place to buy strings.
